Armadillos generally spend the day sleeping in the safety of burrows. They may have as many as twelve burrows located throughout their range, which they dig with their strong front claws, kicking away the excavated dirt with their hind legs.

Each burrow may be from 20 inches to 12 feet below the surface of the ground. The burrow consists of a labyrinth of tunnels that can be as long as 23 feet. Two or more of the tunnels have nest chambers, which the animal lines with grass and weeds.

Nine-banded armadillos will share their burrows only with members of the same sex. Each animal has its own territory, but those of males often overlap. Territories are marked with scent.

Days are spent in whichever burrow is nearest at the end of the night's wanderings.

The hard bone plates covering the body provide effective armor against attack. The plates are arranged in bands over the middle of the back and are attached to flexible skin. Fore and hind limbs have strong, curved claws for digging in the ground Armadillos dig to find food, to make nest burrows, and to escape predators such as jaguars, pumas, and coyotes. The armadillo's underside has no armor. The nine-banded armadillo protects itself by lying flat on the ground with its legs tucked under the shields on its shoulders and hips.

Mating takes place during the summer, but the exact time varies according to location. Since armadillos have poorly developed senses of sight and hearing, it is thought that the males rely on their sense of smell to detect when a female is ready to mate.

After mating, the fertilized egg is not implanted into the female's uterus wall for 3 months. This delays the birth of the young until the following spring, when more food is available.

At night, the armadillo emerge from its burrow to look for food: insects, small animals, birds' eggs, fungi, roots, fruits, and carrion (rotting animal flesh). It uses its strong sense of smell to detect food. Its long snout has particularly sensitive nostrils.

In the southern parts of its range, the nine-banded armadillo feeds on ants and termites. It pokes its long, sticky tongue into the nest holes and draws out both the insects and their larvae.

If food is detected underground, the armadillo begins to dig frantically. It uses its powerful forelegs to loosen the soil and, balancing on its forelegs and tail, kicks away the dirt from beneath its body using its hind legs.

DID YOU KNOW?

The nine-banded armadillo is the only armadillo species that can swim. It does this by inflating its stomach and intestines with air to keep it buoyant. It can also cross a small river or stream by walking on the bottom while holding its breath.

Using its long, sticky tongue, the armadillo can eat more than 40,000 ants at one feeding.

Armadillos sometimes fall asleep on their backs, away from the safety of their burrows. When they do, they expose their vulnerable underside to attack from predators.

The name armadillo comes from the Spanish word armado, which means "one that is armed"..

When digging for prey, the armadillo avoids getting dust up its nose by holding its breath for up to 6 minutes.
